Behavioral Methods Flashcards
General Principles
Used to screen for new drugs
Document the pharmacologic profile of the drug
Characterize the effective dose range relative to side effect profile
Separate the acute vs chronic effects of the drug
Operant Conditioning
Uses consequences to affect behavior
Modifies voluntary behavior
Differs from Pavlov, in that Pavlov deals with behaviors that change with the antecedent
Positive Reinforcement- Reward to encourage behavior
Negative Reinforcement- Remove punishment to increase behavior
Positive Punishment- add punishment to decrease behavior
Negative Punishment- Remove reward to decrease behavior
Avoidance Learning
When a behavior results in the cessation of an aversive stimulus
Extinction
When a previously reinforced behavior is no longer reinforced, its frequency decreases
Non-Contingent Behavior
Decreases a behavior by reinforcing an alternate more desired behavior instead
Drug Discrimination
Technique used to determine the degree to which a novel drug is similar to a standard drug Not unlike human to identify drug class after taking drug
Conditioned Place Preference
Technique similar to drug discrimination, used to determine the degree to which a novel drug is similar to a standard
Animals are monitored for which box arm they enter
Self Administration
Gold Standard
Animals self administer the same drugs as humans
Drugs of abuse enhance brain stimulation reward or lower threshold for reward
Drugs of abuse enhance neuronal activity and/or neurotransmitters in reward relevant brain circuits
Prep Animals for Self Administration
Train animals to press lever for food pellets
Animals prepared with IV catheter
Recover from surgery
Change session to deliver a reinforcing dose of a drug for each lever press
Gradually increase the number of lever presses
Progressive Ratio
Self administration paradigm to see how many lever presses the animal would do for a reinforcer
Break Point
The number of lever presses an animal is willing to do for a single reinforcer
Conflict
Used to detect antianxiety within a drug
Pairs a reinforcer with a punisher in the same session
Approach avoidance situations cause anxiety
Standardized Questionnaires
Profile of Mood States (POMS)
Used to identify and assess transient and fluctuating affective mood states
65 items, self reported, a brief version contains only 30 items
Can be administered in 5-10 minutes
Subjective Mood Assessments
Visual Analogue Scale (VAS)- measurement instrument that allows subject to rate mood or perception that is not easily measurable by other means
Body Sway
Measures a participant’s ability to stay upright and steady
Measures proprioception and balance
Useful in quantifying side effects of medications
